Bk. IX. Ch. II. CHUKCHE8 WITH STONE KOOFS. 431 havino' a clear width of 45 ft. 6 in. The internal dimensions of the church are 177 ft. by 115. There are three great piers in the length, which carry bold trans- verse ribs so as to break the monotony of the vault, and have between them secondary arches, to carry the galleries There is another church at the same place, the roof of which is of a somewhat more com- plicated form. The internal length, 140 ft., is divided into tliree by transverse arches; but its great peculiarity is that the vault is cut into by semi-circular lunettes above the screen side-walls, and through these the light is introduced. This arrangement Avill be understood from the section (Woodcut No. 866). Taken altogether, there is probably no other church of its age and class in which the vault is so pleasingly and artistically ar- ranged, and in which the mode of introduc- ing the light is so judicious and effective.

F. del.) last churches is not verv well ascertained. They probably belong to the 5th, and are certainlv not later than the 6th century ; but, before we can speak with certainty on the subject, more examples must be brought to light and examined. From our present knowledge it can hardly be doubted that a sufficient number do exist to complete the chapter ; and it is to be hoped they will be published, since a history of vaults in the East, independent of domes, is still a desideratum. 866.
